PAPER-FOLDING MACHINE.

T0 aZZ whom it may concern:

Be it known that I, TVALTER G. TRAUTMAN, a citizen of the United States of America, residing at Cleveland Heights, in, the county of (luyahoga and State of Ohio, have inventedcertain new and. useful Improvements in Paper-Folding Machines, of which the following is a specification.

My invention relates to improvements in plied to the well-known type of paper-fold ing machine adapted to produce a signature of sixteen or less pages, in association with which my novel auxiliary paper-folding mechanism is adapted to be used for producing a signature of thirty-two pages at will, or merely delivering the sixteen page Slgllfl ture to the stacker device. Thus, my improvements comprise a conveyor table inter mediately positionedbetween the paper-fold ing machine and a set of buckling and folding rolls, one of which is made ad ustable in connection with the folding plate for rendering the latter inoperative. The stacker mechanism associated therewith is provided with means for elevating it approximately to the level of the buckling rolls or lowering it to a position for receiving the signatures from the folding rolls. In addition, a deflector is provided with automatic means for adjusting it to engage and direct th signatures alternatively in the upper or lower position of the stacker device.

The features of my improvements may be more readily explained by making reference to the accompanying drawings wherein Fig. l is a view of my improved mechanism in side elevation; the stacker being shown in its lowermost position.

Fig. 2 is a longitudinal sectional view thereof; certain rolls of the associated paperfolding machine and the frame being shown broken away in both of said figures to indi cate the relationship.

mechanism in side elevation showing the stacker device ,in its upper position of adjustment and the foldin plate and folding roll in inoperative position.

Fig. 4: is a longitudinal sectional view thereof; both of said figures being shown laterally broken away.

- Fig. 5 is a transverse sectional view on the irregular line 55, Fig. 1.

Fig. 6 is a fragmentary detail View showing the adjusting means for the deflector and for the folding roll, and

Fig. 7 is a fragmentary section thereof on line 77, Fig. 6.

Throughout the several figures of the drawings I have employed the same characters of reference to indicate similar parts.

Reference may first be made to Figures 1 and 2 wherein the rolls a a a of the associated paper-foldingmachine are shown with the frame I) and gear 0 in position for delivering the signatures to the conveyor table (Z of my improved auxiliary apparatus. This conveyor table is adapted to deliver said signatures to the buckling rolls e f which will direct them into the folding plate 9 and from which these signatures will issue to be folded between the folding rolls f h. From thence said signatures will be directed by the adjustable deflector plate 2' between the paired feeding rolls j j which normally pass said signatures in the illustrated positions of adjustment to the traveling belt of the stacker device Z2. This is the normal adjustment of the apparatus for producing the thirty-two page folded signature and the operation will be readily understood from the above by those skilled in the art.

However, it commonly iS.-found desirable to omit certain folds in a paper-folding machine, including the last folding operation above indicated, While delivering the signatures to the stacker device as before. My present improvements contemplate this altercd operation by means of the features of construction and adjustment which I shall now describe.

Referring now to Figs. 3 and 4, it will be seen that the folding plate 9 has been elevated and retained out of normal operative position while the pivotally mounted folding'roll it has been turned on brackets it above the level of the buckling rolls 6 f. In addition thereto, it will be ob- Q I masses served that the stacker device it has also been elevated from its lower receiving posi tion, together with the rolls y" and the de flector 27, so that the latter is above the meet ing plane of the rolls a f. Tl" his is accomplished by means of the interconnected lever mechanism Z Z and the laterally positioned interposed cams Z which operate against the rolls m and serve to elevate the stacker and its associated mechanism upon the slide n. The lever Z is secured to the cam shaft 0 and is held in its upper position by means of a bolt 0 which enters the socket 0 provided on the frame. Said frame is adjustable as a whole by means of the screwactuated standard 79, so that the auxiliary mechanism may be adjusted to insure the proper level thereof with respect to the associated paper-folding machine.

Further details of the automatic actuation of the deflector plate 2' may be explained by referring to Figs. 5, (3 and 7 showing said plates mounted upon the shaft i and tensioned by the spring 2'. A roller 2' is adapted to engage the side-rail i as the stacker and its associated mechanism are elevated by the cam, so that the deflector plate will be turned sufliciently to clear the lower roll 7 and assume the upper dotted line position of Fig. 6. This enables it to deflect the signatures from the rolls 6 j to the rolls j, and thence to the belt 70 of the stacker, as previously explained.

Referring now to Fig. 3, it will be ob served from the dotted line showing at the left, that the stacker device is supported on terminally flattened trunnions 7a which may be inserted within the recess 7* of frame 1' by inclining the stacker device approximately in a45 position with respect thereto. It is then actuated into a substantially horizontal, full-line-position where it is held by the bolt r with its gearing in operative relation with the gearing of the auxiliary mechanism as shown in Figs. 1 and 3.

From the foregoing it will be seen that i the apparatus is adapted alternatively for supplying the 32-page fold previous to ad vancing the signatures to the stacker, or it may readily be adjusted for .conveying the iii-page signatures direct to the stacker without imparting a fold thereto. This is accomplished by means of the several adjustments previously described, without loss of time, thereby facilitating the operation of a paper-folding machine very materially. Having now described the preferred em bodiment of my invention and briefly: detailed the operation and advantages thereof, I claim as new and desire to secure by Letters Patent the following:
